,Be it known that I, CLAU EH. MoQUIn- LAN, a citizen of the United States, and a resident of Green Bay, 1 in the, county of Brown and State ofWiseonsin, have made certain new and useful Improvements in;

Film=Feed Apparatus for Projection Devices, of which the following is a spec1fi-, cation. V Q

My present, invGhtiOn; relates generally to moving picture and other projectors, and more-particularly to film feeding d ev1ces therefor, my object being theprovislon of simple effective means whereby the film may be, fed through the. projector box from a holder in the same condition; that it .GOmes from the take up reel so as to avoid extra hand ing of .the' lm in 'e me the ame as isnow required'between feedingopera tions.

It is well known-at the present time that.

a" film passing through a projecting box from the feedlng reel, is wound from the center out upon the take up reel and must then be set up and reversed from the take up reel to the feedreel before it can beagain fed from the latter-through the projecting box, ,This gives rise to handling of the film to an undesirable extent as the" film is sub jected to a great deal of wear, particularly during the reversing operation due to careless operators, and does not receive the same care asfit does when fed through the pro;

jecting'box; r

jMy invention proposes a film holding and feed d'evicefrom which-the. film may be fed fromits center into and through the projecting box and from the latter on to a take up wheel, the hub and one side of which are detachable with respect to the opposite side,

Specification of Letters Patent.

Referringnowtothesefigures, and pa'rticularly Fig. 1, I 'havesliown a projecting box at 10 .which ;may be a moving picture machine or other projector, having a. film receiving opening in its upperwall indicated at 1 1 in Fig. 2, and having a film'out; let opening in its base, the latter above a.

rotatablymounted and d-riVentakeTup roll Patented Aug. 9, 1921.

consisting of inner andouter. side plates 12 a and '13, and acylinder hub. 14, the latter ofwhich is provided at, opposite edges with radially outstanding lugs 15,.as particularlyshown Tin Fig 6, adapted for. rOtativemove- Inent relative to the side plates 1-2 -and -13 beneath and ,away' from laterally oifset sprlng fingersjfi, which are up-set from the. lnner surfaces of theside plates, as seen by a comparison ofFigsB and5. The hub lt also has a slot 17 in its wall zinwardly throughwhich the freeend of thefilm 18 may be extendedfor engagement beneath a springelip 19, mounted upon an inner segmental wall'20 of the hub and itis thus obvious that witlrthe free end of the film so attached, andwiththe parts in. the op erative position shown in Fig. 1, rotation of the reel on its shaft shown in dotted lines at 21; in Figs; 131K 37 Willcause the film to windbetween the side plates. nlVhencompletely'w'ound, the film may be entirely dis-4 associated from the take-up reelbyfirst removing the L outer side plate from the inner d pla e af e ic a p ihsh d 2 1 iniFig; 4t; whose overlapping endsextend through an adjusting loop23,'i is placed around thefilm andthe latter freed at its center from the hubjl tw It is' thusobvious the, film is in] this condition, adaptable T to feeding:- f m t rjah t Will e h it .flfhmiF g- 2 th the a isf f e e d ably less width than thatof the film, for a purpose which will be presently described.

The feed reel or holder consists of a circular plate 24 shown particularly in Fig. 2, having a depending axial tube 25 adapted to telescope the upper end of a tubular uprlght 26 secured 'on the projecting box 10 and com closed thereby is disposed on the plate, this attaching screw receiving a wing nut 31, as in Fig. 2, below the plate 24, so that the film is thus securely held in proper position.

The plate 24 has a surrounding flange 32, the upper edge of which extends above the film when the film is disposed on the plate and receives a cover 33 having a central upright 34 whose base 35 is secured to the.

cover at the inner ends of radial slots 36. The cover also hasdiametrically opposed outstanding straps 37 and 38, the former of which is of the angular shape shown in Fig;

1, and is hinged at 39 to a supporting bracket 40, so thatthe cover 33 will thus be p raised and lowered with respect to the feeding reel 24. The other strap 38 rests. in the lower positionupon a second bracket 41 upstanding from the projection box 10 and the slots 36 receive the lower portions of arms 42 in slidable relation thereto. These arms have bearings at their lower ends for film engaging rollers 43, provided with convex surfaces, which extend into engagement with the inner peripheral portion ofthefilm roll and continuously press outwardly upon the same by virtue of the hinge connections 44 between the upper ends of the-arms 42 and a weight/45 slidable vertically onthe upright stem 34 of the cover.

It is thus obvious the film, disengaged from the take up roll in the manner previously described, may be readily disposedand secured within the feeding reel and in flatwise relation upon the plate 24 so that by lowering the cover 33after the weight 45 has been elevated on the upright stem 34, the several rollers 43 may beextended with in the film roll and into engagement with the inner surface thereof. During operation the plate 24 with the film, rotates while the cover 33 remains stationary, and furthermore rotates at a speed conforming tothe feed of the film downwardly through'the projectingbox, and at a speed equalingthat of the take-up roll at all times, for. instance by driving the belt 29 from the same source as that from which the projecting apparatus is actuated. This avoids the necessity at present of varying the relative. speed of the take-up andfeed rolls where the film is'fed from the outer periphery of the feed roll and. wound upon-the inner periphery of the take-up roll.

If so desired,a roller-46 may be mounted on the lower end of the stem 47 ,whose upper threaded vportion extends vertically through one of the slots 36 of the cover and receives a'wing nut 48 for clamping the same adjustably in place, this roller'46 being adapted to be adjusted into movable engagement with theouter periphery of the film roll as seen in Fig. 2, above the band 22."
